What communicates with the hardware?

Hear this out loudPauseSoftware is stored in the hardware as magnetic domains on the hard drive or floppy disc, or as low and high voltages in computer chips. When you type on a keyboard, each character is converted into an electrical series of 0’s and 1’s which are then stored as low and high voltages in the computer chips called RAM.

How does the hardware device communicate with the computer?

Hear this out loudPauseHardware communication is done by using an interrupt request (IRQ). Each time hardware needs the attention of the computer the interrupt controller sends the request (INTR) to the CPU to stop what it is doing to process the request.

Which device helps in processing commands?

Hear this out loudPauseThe CPU (Central Processing Unit) is the part of a computer system that is commonly referred to as the “brains” of a computer. The CPU is also known as the processor or microprocessor. The CPU is responsible for executing a sequence of stored instructions called a program .

How does an application send commands to a device?

Mechanisms like mobile Short Message Service (SMS) can send wakeup signals to transition these devices to a fully operational state. The application sends commands to devices using the ServiceClient API. One instance of ServiceClient can send messages and invoke methods for multiple devices.

Are there any commands to check hardware information?

7. Inxi Inxi is a 10K line mega bash script that fetches hardware details from multiple different sources and commands on the system, and generates a beautiful looking report that non technical users can read easily.

How does the operating system work on a computer?

This is where the Operating System comes in. The OS provides an API to manage groups of related devices, and provides hooks for hardware vendors to provide the translation between the OS commands, and the commands the microcontroller understand. In Windows land, this is a driver.
